Based on leaked release notes, Apple-watching blog 9 to 5 Mac see the next OS X as arriving June 8, with some modest UI upgrades, a big push on 64-bit, and presented by Steve Jobs himself.

That date is based in part on speculation about why Apple would book a six-day block at a convention center and dub it only a "Corporate Meeting," but the release notes seem pretty solid, or at least crazily detailed for a forgery. The most recent build notes indicate a new QuickTime Player with a minimal interface, Safari 4 beta included as the default browser, and a "new Cocoa Desktop, Info Window and Contextual Menu" for Finder. Is this a nice set of improvements for a solid OS, or do you see Apple concentrating their efforts elsewhere? Tell us your take in the comments.
